Who were the winners and losers on Saturday at Olympic Club? It's time to take a closer look with another edition of birdies and bogeys.

Birdie: Graeme McDowell

This journey for McDowell began not far from Olympic, down the coastline at Pebble Beach. Following a monster 2010 season that featured wins in the U.S. Open, a clinching birdie putt in the Ryder Cup and a successful head-to-head duel with Tiger Woods, McDowell admitted to a "hangover" in 2011. He resolved to regain focus this year, and the evidence of his progress was on display Saturday, when McDowell's brilliant back-nine charge gave him a 68 and put him in a tie for the lead heading into Sunday. If he were to prevail, it would mark three-straight wins for Northern Ireland in the U.S. Open, and the country's fourth major title in three years.
